David Adams can tell you the exact moment the car changed his life.In 1971 he was a 17-year-old senior at Beaverton High School and an accomplished artist and sculptor who already had pieces displayed in Portland galleries.Then, one afternoon, during lunch break, he and a friend walked from campus to a nearby fast food restaurant. And that’s when he spotted the roadster.”It was sleek. Sexy. And it smelled of leather, wood and musty wool carpets,” Adams recalls.And he was in love.The Jaguar wasn’t for sale, but a fellow student knew of one just like it, in better shape, that the owner wanted to get rid of.”I borrowed $200 from a buddy for the down payment and my parents helped me get the financing for the rest,” he says. “It cost $700.””In 1971 it wasn’t a classic,” he says. “It was just a used car.”
